BUILDING CUSTOM GLYPH RANGES
---------------------------------
You can use the ImFontAtlas::GlyphRangesBuilder helper to create glyph ranges based on text input.
For exemple: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.
ImVector<ImWchar> ranges;
ImFontAtlas::GlyphRangesBuilder builder;
builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
builder.AddChar(0x7262); // Add a specific character
builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, ranges.Data);

All your strings needs to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese CP-1251 for Cyrillic) will NOT work!
In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
You can also try to remap your local codepage characters to their Unicode codepoint using font->AddRemapChar(), but international users may have problems reading/editing your source code.

Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code.
Also read releases logs https://github.com/ocornut/imgui/releases for more details.
- 2017/07/30 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
- 2017/08/11 (1.51) - renamed ImGuiSetCond_*** types and flags to ImGuiCond_***. Kept redirection enums (will obsolete).
- 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
- 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
- changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
- changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0,0))'
- 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse

e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change.
e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense!
Q: How can I tell when ImGui wants my mouse/keyboard inputs and when I can pass them to my application?
Q: How can I tell when ImGui wants my mouse/keyboard inputs VS when I can pass them to my application?
A: You can read the 'io.WantCaptureMouse'/'io.WantCaptureKeyboard'/'ioWantTextInput' flags from the ImGuiIO structure.
- When 'io.WantCaptureMouse' or 'io.WantCaptureKeyboard' flags are set you may want to discard/hide the inputs from the rest of your application.
- When 'io.WantTextInput' is set to may want to notify your OS to popup an on-screen keyboard, if available (e.g. on a mobile phone, or console without a keyboard).

Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
A: When loading a font, pass custom Unicode ranges to specify the glyphs to load.
All your strings needs to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese or CP-1251 for Cyrillic) will not work.
In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
You can also try to remap your local codepage characters to their Unicode codepoint using font->AddRemapChar(), but international users may have problems reading/editing your source code.
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application
// Add default Japanese ranges
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
As for text input, depends on you passing the right character code to io.AddInputCharacter(). The example applications do that.
// Or create your own custom ranges (e.g. for a game you can feed your entire game script and only build the characters the game need)
ImVector<ImWchar> ranges;
ImFontAtlas::GlyphRangesBuilder builder;
builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
builder.AddChar(0x7262); // Add a specific character
builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, ranges.Data);
All your strings needs to use UTF-8 encoding. In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax.
Specifying literal in your source code using a local code page (such as CP-923 for Japanese or CP-1251 for Cyrillic) will NOT work!
Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
Text input: it is up to your application to pass the right character code to io.AddInputCharacter(). The applications in examples/ are doing that.
For languages using IME, on Windows you can copy the Hwnd of your application to io.ImeWindowHandle. The default implementation of io.ImeSetInputScreenPosFn() on Windows will set your IME position correctly.
Q: How can I preserve my ImGui context across reloading a DLL? (loss of the global/static variables)
A: Create your own context 'ctx = CreateContext()' + 'SetCurrentContext(ctx)' and your own font atlas 'ctx->GetIO().Fonts = new ImFontAtlas()' so you don't rely on the default globals.
Q: How can I use the drawing facilities without an ImGui window? (using ImDrawList API)
A: The easiest way is to create a dummy window. Call Begin() with NoTitleBar|NoResize|NoMove|NoScrollbar|NoSavedSettings|NoInputs flag, zero background alpha,
then retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like.
You can also perfectly create a standalone ImDrawList instance _but_ you need ImGui to be initialized because ImDrawList pulls from ImGui data to retrieve the coordinates of the white pixel.
- tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code.
- tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug"
